Dr. C. H. Eigenmann in British Guiana, constitute the nucleus of a very 

 large and important collection representing the ichthyology of Brazil and 

 adjacent countries. 



The Director of the Museum has just returned from Utah, where he 

 had an opportunity to examine the work which is being done by Mr. Earl 

 Douglass in Uinta County. Mr. Douglass has opened a quarry at the 

 summit of one of the peaks lying west of the Green River, south of the 

 point where it breaks through Split Mountain on its passage from Wyo- 

 ming into Utah. Thus far this quarry has yielded the remains of seven 

 separate dinosaurs, three of which are evidently carnivorous dinosaurs 

 remarkably well preserved. The other four are sauropod dinosaurs, one 

 of them apparently a Brontosaur of large size, the bones of which are 

 remarkably well preserved and apparently have suffered hardly any dis- 

 location. Mr. Douglass has succeeded thus far in recovering between 

 forty and fifty caudal vertebrae lying in a complete series from their union 

 with the sacrum onward toward the extremity of the tail. The pelvic 

 girdle is in position and near by is the femur. A large number of ribs and 

 dorsal vertebras have already been uncovered. One of the most inter- 

 esting discoveries is a series of colossal cervical vertebrae which measure 

 about four feet from the top of the spines to the base of the cervical ribs. 

 They apparently have sustained no crushing. Whether as the work pro- 

 gresses it will be found that these remarkable cervicals pertain to the large 

 skeleton already alluded to, or represent portions of a still larger sauropod 

 dinosaur, cannot as yet be positively stated. The work which is being 

 done in extricating these remains is one of great difficulty and attended 

 with considerable expense, as the material in which the bones are imbedded 

 is hard sandstone. 



Familiar as the writer is from personal knowledge with all the principal 

 quarries which have been opened in the United States in the past and 

 from which dinosaurian remains have been taken, he does not hesitate 

 to say that the present quarry, so far as it has been developed, is appar- 

 ently richer and the specimens better preserved than in any similar open- 

 ing which has been made. It may best be compared with the famous 

 quarry of Professor Marsh at Canon City, which was subsequently oper- 

 ated by the Carnegie Museum, and from which Mr. Hatcher took a quan- 

 tity of valuable material; but the specimens are better preserved and 

 have experienced far less dislocation than in that famous deposit. The 

 bones in the quarry opened by Mr. Douglass have apparently not been
